Automatic processing machine for header

Abstract

An automatic processing machine for header includes a frame ( 1 ), a pipe clamp ( 21 ), a punch assembly ( 22 ) and a translation mechanism ( 23 ) which can drive the pipe clamp ( 21 ) and the punch assembly ( 22 ) to slide. The pipe clamp ( 21 ), the punch assembly ( 22 ), and the translation mechanism ( 23 ) are all positioned on the working table ( 101 ) of the frame ( 1 ). The translation mechanism ( 23 ) includes a first slide seat ( 231 ) sliding along X axis. One of the pipe clamp ( 21 ) and the punch assembly ( 22 ) is positioned on the first slide seat ( 231 ) and the other is positioned on the frame ( 1 ). A separator transferring device ( 3 ) is also positioned on the working table ( 101 ) for transferring the separator into the pipe. The separator transferring device ( 3 ) and the pipe clamp ( 21 ) are separately positioned on either side of the punch assembly ( 22 ). The automatic processing machine for header combines a hole punching device with a separator transferring device, thereby improving the processing efficiency.
